Original 1927 advertisement for Dunlop Pyorrhea Paste by The Dunlop Pyorrhea Machine Manufacturing Company, 282 East 6th St., Saint Paul, Minnesota. Carefully removed from a vintage 1927 publication; it measures about 5.25 x 3.75 inches. Light even toning and small binding holes along one edge from removal; no tears seen.

The ad shows the labeled tube ("Pyorrhea Paste, Dunlop, 20% Alcohol, for the treatment of Pyorrhea and Mouth Diseases") and urges its use by dentist and patient for trench mouth, pyorrhea and tissue infections of the mouth.

An unusual dental advertising piece for dentistry and pharmacy collectors, Minnesota history, a dental office wall, or junk journals.
